which powerhead would you choose
 

ok, i have to pick between:

1. Top Fin 150
2. Penguin 1140

which would be better, just using for some extra flow in the tank.

I think im leaning toward the penguin

Penguin

why only those two

I have to do an exchange at petsmart... I purchased an emergency heater, but ended up not using it... i waited to long and am stuck having to do an instore credit. I need a new power head, and these two are the ones that was most interested.

they dont have much of a selection
